CBO projects federal debt will hit 120% of GDP by 2035, exceeding historical highs, with deficits worsening by $1.4 trillion over the decade largely due to Trump's tax cuts, tariffs, and immigration enforcement.
The Congressional Budget Office released its 10-year fiscal outlook Wednesday, projecting that federal debt held by the public will rise from 101% of GDP to 120% by 2035, exceeding historical highs. The projected 2026 deficit is about $100 billion higher than last year's estimate, with total deficits from 2026 to 2035 now $1.4 trillion larger than previously forecast.
The deteriorating outlook stems largely from major policy changes over the past year, including Republicans' 'One Big Beautiful Bill Act,' higher tariffs, and the Trump administration's immigration enforcement crackdown. The CBO notes that while tariffs will raise federal revenue by $3 trillion, they also bring higher inflation from 2026 to 2029. Congressional Budget Office projections indicate inflation won't hit the Federal Reserve's 2% target rate until 2030.
Rising debt service costs matter because repaying investors for borrowed money crowds out government spending on infrastructure, roads, and education that enable future economic growth. Jonathan Burks of the Bipartisan Policy Center called the large deficits 'unprecedented for a growing, peacetime economy,' though he noted there is still time for policymakers to correct course. The Peterson Foundation's Michael Peterson warned that voters understand the connection between rising debt and their personal economic condition, calling debt stabilization essential to improving affordability.
Editor’s rationale — The CBO's official 10-year fiscal projection represents a significant institutional development affecting nationwide fiscal policy and economic planning, with durability extending years into the future. However, the novelty is moderate—this is an expected periodic CBO report rather than a policy change itself, and the deterioration of fiscal projections has been widely anticipated given recent legislative actions. Verification is strong through primary CBO sources and official statements, though some analytical commentary is included.
